  1. 1. Condensation irrigation : a combined system for desalination and irrigation

    Författare :Jenny Lindblom; M. Thameur Chaibi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Condensation Irrigation (CI) is a new irrigation method that combines desalination and subsurface irrigation by making use of saline water for supplying clean irrigation. In this system, solar stills are used for evaporating non-potable water, and the formed vapour heats and humidifies the ambient air above the water surface. LÄS MER

  3. 2. Condensation irrigation : simulations of heat and mass transfer

    Författare :Jenny Lindblom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : There is a growing water demand in the world. Along with the deterioration of existing water supplies, the escalating world population leads to the assumption that two out of three people will lack sufficient freshwater by the year 2025. LÄS MER

  4. 3. Condensation and frost formation in fibrous thermal-insulation materials

    Författare :Tomáš Vrána; Folke Björk; Ove Söderström; Kjartan Gudmundsson; Carsten Rode; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibrous thermal insulation; Stone wool; Cellulose; MAterial properties; Moisture transport; Condensation; Frost formation; Exterior conditions; Interior conditions; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. LÄS MER

  5. 4. External Water Condensation and Angular Solar Absorptance : Theoretical Analysis and Practical Experience of Modern Windows

    Författare :Anna Werner; Arne Roos; Claes-Göran Granqvist; Svend Svendsen; Uppsala universitet; []
    Nyckelord :Engineering physics; Windows; External condensation; Radiative cooling; Optical properties; Coated glass; External condensation; Radiant cooling; Teknisk fysik;

    Sammanfattning : Part I of this thesis is a theoretical background to parts II and III. Part II treats the phenomenon of decreased visibility through a glazing due to external water condensation, dew, on the external surface. Some simulations are presented where it is shown that under certain circumstances condensation can be expected. LÄS MER

  7. 5. Droplet growth in atmospheric turbulence : A direct numerical simulation study

    Författare :Xiang-Yu (李翔宇) Li; Gunilla Svensson; Axel Brandenburg; Wojciech Grabowski; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cloud micro-physics; turbulence; inertial particles; DNS; condensation; collision; coalescence; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : This Ph.D. thesis examines the challenging problem of how turbulence affects the growth of cloud droplets in warm clouds. Droplets grow by either condensation or collision. LÄS MER
